A standard 20MHz channel offers transfer speeds of up to 150Mbps whereas a 40MHz
channel uses two standard channels and offers speeds of up to 300Mbps. However, not all
devices support 40MHz channels.
Select the channel bandwidth you want to use for your wireless network.
It is recommended that you select 20/40MHz . This allows the NWA1121-NI to adjust the
channel bandwidth depending on network conditions.
Select 20MHz if you want to lessen radio interference with other wireless devices in your
neighborhood or the wireless clients do not support channel bonding.
